Their latest project is a based on the Lamborghini Murcielago LP640 and they call it Murcielago TT.
In stock LP640 has 640 horsepower, now after Heffner Performance modifications this Italian supercar has over 1100 hp at 1 bar of boost.
According to Heffner in a 90 degree heat the car pulled off a 5.10 second 60-130 mph sprint at around 950 hp. For stock Murcielago it takes around 9.5 seconds to make the leap from 60 to 130 mph.
Guys at Heffner Performance will continue to test the car at various boost levels and hope to dip 60-130 mph sprint into the 4 second range.
